PHP - Php Table With Prime Numbers

hi , how to get the prime numbers of the positive integer input and print them?

here's what i have at the moment

function getPrime($num){
  if((int)$num == $num && (int)$num > 0){
    for($i = 2; $i < $num; $i++){
      for($j = 2; $j < $i; $j++){
        if($i % 2 == 1){
          echo $i.'<br />';
        }
      }
    }
  }
}

displayPrime(10);


the ouput should be

Code: [Select]
2,3,5,7
but the output apparently, is

Code: [Select]

3
5
5
5
7
7
7
7
7
9
9
9
9
9

how to solve this?

Hey all -

What is the appropriate syntax to echo out each character name (vanity_name), and their total number of "ties" "wins" and "losses"

Thanks for your help!

$q1 = "SELECT Wins, Ties, Losses from game_char WHERE vanity_name='mario'";
$mario_sql = mysql_query($q1);

Code: [Select]
<?php echo "Mario: " . $mario_sql; ?>

I have this code: <td><form action="" method="post" name="TableData" class="style5" id="TableData">
                  <table width="800" border="0" bordercolor="#000000" background="Assets/Tablebar.gif">
                    <!--DWLayoutTable-->
                    <tr>
                      <td width="183" height="20" align="center"><div align="center" class="style11 style1"></div></td>
                      <td width="317" align="center"><div align="center" class="style11"><span class="style2"><?php echo $row_TableData['UserID']; ?></span></div></td>
                      <td width="136" align="center"><div align="center" class="style11"><span class="style2"><?php echo $row_TableData['UserName']; ?></span></div></td>
                      <td width="136" align="center"><div align="center" class="style2 style11"><span class="style11"><span class="style2"><?php echo $row_TableData['Score']; ?></span></span></div></td>
                      <td width="103" align="center" valign="top"><span class="style2 style11">
                        <?php
  for($i = 0; $i < $row_TableData['TourWins']; $i++) {
   echo '<img src="Assets/Medal.gif" />';
  }
?>
                      </span></td>
                    </tr>
                  </table>
              </form>            </td>   The Table displays fine and it sorts fine win Highest to lowest score, I am wanting to put place numbers Like 1,2,3,4 etc in the first Colom which is in bold, but I don't know what to use. any help would be great.

How would I compare 2 random numbers to rows in a table.  The table has 4 rows and 2 colums.  My table is setup like this: ID hp mp then has just randomly placed numbers from 0 to 5.  So far my script looks like this: I have $new_hp=rand(0,5); $new_mp=rand(0,5).  Then i query the db by $myquery=doquery("select hp,mp from users";  $myrow=mysql_fetch_array($myquery); once this is done would a while statement like while ($myrow = mysql_fetch_array($myquery) to what each line in the table has?  I would then need to compare the random numbers to those entries in the database.  Something like if($myrow[hp] == $new_hp && $myrow[mp] == $new_mp) { ?  But if the if statement isnt true it needs go back choose another random number and run same again and again until the statement is true and that is where im stuck at so any help would be greatly appreciated

Hi,
I need to sort variables in groups of up to 15 and put it in an array. For example:
$exstract['center_tabOpBody_0'] =5
$exstract['center_tabOpBody_1'] =6
$exstract['center_tabOpBody_2'] =8
$exstract['center_tabOpBody_3'] =1


Should yield:
ARRAY(
          = center_tabOpBody_1,center_tabOpBody_2,center_tabOpBody_3 // <-----15 [1] = center_tabOpBody_0 //<----5
)

Is there some simple function do do the "efficiency" sort?

Thanks,
Vadim
